Impact of age on autoimmune hepatitis: A comparative study of patients diagnosed before and after sixty

Figure 1 Patient selection flowchart. Out of 160 patients with a clinical diagnosis of autoimmune hepatitis, 132 had biopsy-confirmed disease. After excluding 35 patients due to incomplete data, 97 patients with at least 12 months of follow-up were included in the final analysis. These were stratified into two age groups: (1) 57 patients younger than 60 years; and (2) 40 patients aged 60 years or older. AIH: Autoimmune hepatitis.
